Description and Introduction

3.3V 20Mbps RS485/RS422 Transceivers with Integrated Switchable Termination The LTC2854CDD is a product from Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Type:** RS485/RS422 Transceiver  
- **Package:** DFN-8 (3mm x 3mm)  
- **Operating Voltage:** 3V to 5.5V  
- **Data Rate:** Up to 20Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** 0°C to 70°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Shutdown Mode):** 1µA (Max)  
- **Supply Current (Active Mode):** 1.2mA (Typ)  

### **Descriptions:**
The LTC2854CDD is a high-speed, low-power RS485/RS422 transceiver designed for robust communication in noisy environments. It operates from a single 3V to 5.5V supply and supports data rates up to 20Mbps. The device features enhanced ESD protection (±15kV HBM) and includes a fail-safe receiver that ensures a logic-high output when inputs are open, shorted, or terminated but not driven.

### **Features:**
- **Low Power Consumption:** 1.2mA typical supply current in active mode.  
- **High-Speed Operation:** Up to 20Mbps data rate.  
- **Wide Supply Range:** 3V to 5.5V operation.  
- **Robust ESD Protection:** ±15kV HBM on transceiver pins.  
- **Fail-Safe Receiver:** Ensures a logic-high output for open, shorted, or unterminated inputs.  
- **Half-Duplex Operation:** Single driver and receiver pair.  
- **Thermal Shutdown Protection:** Prevents damage during fault conditions.  
- **Small Form Factor:** 8-lead DFN package (3mm x 3mm).
